  [33X[0;0YThe code for the [5Xtoric[105X package was written during the summer of 2002. It was
  put into [5XGAP[105X package format in the summer of 2004.[133X

  [33X[0;0YThis  documentation was prepared with the [5XGAPDoc[105X package of Frank Lübeck and
  Max  Neunhöffer. Moreover, a bug in toric 1.8 was fixed with the help of Max
  Horn,  and  this  documentation  was  modified accordingly. Finally, I thank
  Olexandr Konovalov and Max Horn for transferring this package to the new Git
  repository.[133X
